An acoustohydrophysical complex for tomographic ocean surveillance is described. The complex has been developed within the framework of the US–Russia project JESAEX (The Japan / East Sea Acoustics Experiment). Technical characteristics of self-contained and mobile receiving and transmitting systems of the complex allow one to use them as building blocks in constructing tomographic systems of various configurations and complexities. Experimental tests of methods and facilities in September–October 1999 in the Japanese sea have shown that the range of reliable reception of composite phase–shift keyed signals, such as M—sequences, is 700 km at an acoustic pressure produced by a sound source of up to 7000 Pa/m.
